#define T1_SIGMA_0   (1U << 0)

We hold the state of individual data points for the T1 encoder using a single 32-bit flags word to hold the state of 4 data points.

This corresponds to the 4-point-high columns that the data is processed in.

These #defines declare the layout of a 32-bit flags word.

This is currently done for encoding only. The values must NOT be changed, otherwise this is going to break a lot of assumptions.

#define T1_SIGMA_NW   T1_SIGMA_0

As an example, the bits T1_SIGMA_3, T1_SIGMA_4 and T1_SIGMA_5 indicate the significance state of the west neighbour of data point zero of our four, the point itself, and its east neighbour respectively.

Many of the bits are arranged so that given a flags word, you can look at the values for the data point 0, then shift the flags word right by 3 bits and look at the same bit positions to see the values for data point 1.

The #defines below help a bit with this; say you have a flags word f, you can do things like

(f & T1_SIGMA_THIS)

to see the significance bit of data point 0, then do

((f >> 3) & T1_SIGMA_THIS)

to see the significance bit of data point 1.
